[Android Q&A, Help & Troubleshooting] imachine:
Yes, that is likely, the su installed will, once invoked via adb, ask SuperUser.apk to allow/disallow it from running, and since that doesn't work that is probably why you get a segfault.

From already running Kyobo, go to Settings -> Privacy -> Factory data reset -> Wipe SD - tick that too. By recovery I meant the official recovery, accessible via Settings -> Privacy -> Firmware Upgrade.

I pulled the /data from my device, I removed all user-related data that I found, left some applications for your convenience otherwise it's somewhat pristine. It's about 250MB tgz'ed (1GB unpacked) so it will take about two hours to upload. Posted in post #81.

Yes, problem free. But:

1) Root it like I wrote (I think the cache fix might be important here).

2) Run V6 supercharger.

3) Disable GPS with power widget.

I also fiddled with /etc/permissions/ in order to get Facebook and Twitter I had to tell the device it has GPS - I added tablet_core_hardware.xml like below:

After that I did all according to this post: http://xdaforums.com/showpost.php?p=21871970&postcount=1

And Maps I think (will test this more, ideally I want Network Location to work via WiFi) also hang when I enable GPS with Power Widget. With GPS in Power Widget off, Maps work ok, plus I now have multitouch :)

I now also can find Facebook and Twitter in Google Play store.
